hey guys, i got a .410 shotgun, ive always wanted to shoot some slugs out of it, so the other day i bought some, my question is that on the gun it says for 2 1/2 & 3" ammunition, i looked for some 3" slugs but all i could find is the 2 1/2" slugs. so will this work because i was thinking that shooting a slug is diferent that little pellets, so having that 1/2" gap before the slug starts going down the barrel have any affect on anything?
